# Performance
**You MUST use this skill for ANY performance issue including memory leaks, slow execution, battery drain, or profiling.**
**Bundled tools on Claude Code:** if `command -v <tool>` finds nothing (hooks off or `--bare`), use `<plugin-root>/tools/<tool>` in place of the bare name; `<plugin-root>` is two levels above this skill's `Base directory for this skill:` path.
<!-- AXIOM_AUDITOR_INLINE_BEGIN — auto-maintained by scripts/build-inlined-auditors.ts; do not hand-edit -->
> **Can't launch Axiom agents?** Where this router sends you to an agent, follow its procedure inline. Over MCP, `axiom_get_agent` returns it; elsewhere, read its file below, which needs only file search and read.
>
> Available here: `skills/energy-auditor.md`, `skills/memory-auditor.md`, `skills/swift-performance-analyzer.md`.
>
> For any other agent, over MCP `axiom_get_agent` returns it too; run its xclog, xcsym and xcprof steps with the `axiom_xclog_*`, `axiom_xcsym_*` and `axiom_xcprof_*` tools. Elsewhere, search Axiom's skills for `skills/<agent>.md`; if there is none, do that work yourself with this suite's skills, using any Axiom tool on your `PATH`.
